Arcachon Museum & Aquarium, Arcachon

This museum-aquarium offers a two-in-one sea spectacular. The museum encompasses all aspects - zoological, palaeontological, geological, archaeological and historical of life under the sea (not forgetting oyster farming), while the aquarium uncovers some of the most extraordinary specimens of local sea creatures such as molluscs, crustaceans, fish from the sandy beds and even green turtles. The aquarium's 36 tanks hold a total of 55,000 liters of seawater. Since 1867, the museum-aquarium has worked alongside laboratories at the University of Marine Biology and together they form the marine biology station.
